To all whom' t may concern',

Be it known that'we, OLivER HnQUnRN` Huur and HECTOR Nnurrorr;y J r., citizens of theUnited States, and fresidentsofthe city of St. Louis, Missouri, haveV invented'a new and' useful Window-Sash QOperaftr,l of which the followingis a specification.V

This; Ainvention `relates to sash operating devices. j Y

An objectV of the invention-,is tov provide an improved sashlciperating devicecomprising a longitudinally-movable shaft, a rack in connection with the shaft preferably in such `manner f that the shaft is lcapable Lof rocking movements relative 4to theraclrbut is held against relative longitudinalmovement, actuating devlices coperating with the rack for movingthe shaft longitudinally in opposite directions, and stop devices? arranged to be operated-asian incident 'to the movement ofthe shaft the desired distance in either direction to stop' the actuatingdevices and thereby prevent further movement of the shaft which might resultin 'injury or damage to some of the connections.

lVith the foregoing and other objects in view, we have illustrated a preferred embodiment of the invention in the accompany-ing drawings, in whichf Figure l is a planl view of the sash operating device with the sash in closed `adjustment.

Fig. 2 is a sideelevation thereof. 1

Fig. 3 is an yinner side elevationlshowin'g the stop devices. i Y

Fig. 4t is a plan view further illustrating the stop devices.

Fig. vis a detailed sectionalV view on the line 5 5 of Fig.` 3, showing theconnection between the rack and the axially movable shaft. Y

The shaft 1 is supported for axial movement in roller bearing devices 2. The rack 3 by which the shaftis to be actuated has upper and lower flanges embracing the shaft-between themas illustrated in Fig.V 5. BindingA clips 4 are employed to; attach. the rack in connection with the shaft,-and abutment collars 5y attached to the shaft at.A the ends of therack prevent relative longitudinal movement Lofthe rack and shaft.L The ,shaft'is connectedV to the window sashes by links 6 which are pivoted `toy adjustable clamps ,7 ontheshaft 4and 'to brackets 8 on the window sashes. Links 9 connect the linksf with pivoted brackets 10so as to provide ietlicient,.; strong andfdurable tcggleconnection foractuating the sashes by the axialmovement of the shaft; j

,The rack` 3' extends kthrough the case 1l of thev actuatingdevice and meshes with a pinion 12 within the easel, The pinion12 isin rigid connection witha gear 13 meshing' with a wormrlel on al manipulative shaft 15, so that by turning the shaft ll5 the gear 13 and theA pinion 12 .will also be turned withl the. result that the shaft 1 will be moved axially. Any appropriate, actuating device forA theshaft 15 may beemployed and for convenience we have illustrated a crank wheell. i c The foregoing construction is substantiallythe same in essential particulars as that disclosed inl our `Patent No1,191,923, dated July 18, 1916. ,The present invention comprises,improvements adapted toV be combined with the mechanism abovedelscribed and with any othersimilar sash operator. Inf the form shown a sleeve 17 isattached to the inner end of the shaft'l and is provided with two arms or shoulders 18. The casell is formed with lugs 19 constituting supports for a stop rod 20. lThe stop rod 20'is vadapted to be moved to position to be engaged by one of the projections y18 and thus prevent further rotation of the shaft 15 in yone direction.

A spring arm 2l is attached tov thecase 11 at 22 and, the opposite end of said arm extends through a hole in the rod 20 and normally holds the rod out of the. path of movement of the arm 18.] A stop member 23 in connection with'the rod 2O limits movementv of the rodV by the spring actionA of the spring 21. The clipl, which is on the same side as the spring arm 21, has a projectionw24l adapted to engage with the spring arm and actuate the same in oppolsition to the tension thereof to move the yrod 20 into the path of movement of the projection 18 and thus stop the actuating mechanism from further movementin the direction. in whichit was being operated. The clip t is adjustable and may be placed in Mammoet. a, fait.,

any position desired in connection with the rack so that adjustments may be made to vary the extent of movement-of the shaft l.

The stop device for stopping the actuating mechanism when being operated in the opposite direction comprises a'spring armV 25 secured to the case 11 at 26 and passing through a hole lin a stop rod27 movably supported in lugs 28 in connection With the frame of the actuating mechanism. The

, yspring arm-25is effective normally to hold one v, of

the rod 27 out of ther path of movement of the other projectioni'lS, but iswcapable ofr movement to actuate the rod- 27 into the Vpath of movement of said projection. Outmovementfof th'e'rod27 is effected by aprojection y30 inV connection Withv the clip 4 on v-thesame' side 'of the actuating'meclianism as the spring` arm 25. vThe lug 30 engages the arm 25 and actuatesthe same to move the vrod 27 into the path of movement Vof the projection 1S and'thus stopor lock the actuating mechanism from further movement in ther direction in which it Was being operated.

Since .the clip 4 may be adjusted in diderent positions the extent to which the shaft -1 Will be moved may be optionallyr varied.

The stopping of the actuating mechanism by therod 20 or rods 27 does not prevent reverse ori opposite VVactuation ofthe actuat wing mechanism to move the shaft in theopposite direction. As an` incident to such movement of the shaft in the opposite direction, the projections 24 and 30 will be Vmoved out of contact with the spring arms 21 and `25V .r-espectively, thus enabling said arms to actuate the rodsf20 and 27 respectively out .of the path of movement ofl the projections18. l v

A device of thisfcharacter automatically stops the actuating mechanism and prevents excessive strains being exerted or' thrown upon ,the connections with the Window sashes, or other parts of the device. -The extent'` of movement of theV Window sashes may/.be optionally' variedvbylimiting the extent of movement of the shaft 1, which results from setting Vor adjustingl the clips 4 ,to any desired positions. j Y

We do not restrict'ourselves to the specific construction and arrangement shown, but what We claim and desire to secure by Letters Patent of theUnited States, is
